[rgb]0.,0.,0The extensive experiments based on two different feature encoders, C3D [1]} and I3D [2]} show that our framework MIST is able to produce a task-specific feature encoder. 
[rgb]0,0, 0We also compare the proposed framework with other encoder-agnostic methods on two large datasets , UCF-Crime [3]} and ShanghaiTech[4]}. In addition, we [rgb]0,0,0run ablation studies to evaluate our proposed sparse continuous sampling strategy and self-guided attention module. We also
illustrate some visualized results to provide a more intuitive understanding of our approach. Our experiments demonstrate the effectiveness and efficiency of MIST.
